"The magazine from the federated server may be incomplete. Browse more on the original instance." - why does this appear and how can I turn it off? I cannot log in to other servers to post
I get the point, but the prominence of it makes it look like an error. Frankly, I find it a bit anti federation, like the only reliable content is on-instance.
@ABCDE it's just telling you that having subscribed to a community on another instance after it was created there may be older posts that are not present on your instance and providing you a link to the same community on the home instance if you want to look at older/not yet federated content.
